Should I Replace My Siding When I Replace My Roof?

July 02, 2025 5 Min Read

If you’re thinking about a big home upgrade, you might be wondering if it’s worth tackling both your roof and siding at the same time. Many homeowners feel overwhelmed by the thought of two major projects—and wonder if it’s even possible to handle both together. Let’s break down the real feelings, questions, and practical answers you need to make the best decision for your home.

The answer is: It depends

As with many things, there are a few factors to consider:

Factor 1: What condition is your siding in?

Look out for signs that your siding may need replacing:

1. Visible Cracks or Warping

Cracks, warping, or holes in your siding are clear signs of deterioration.
Warped siding can indicate water damage underneath.

2. Fungus, Mold, or Mildew Growth

The presence of mold or mildew, especially near seams or under panels, could indicate moisture getting behind the siding.

3. Bubbling or Blistering

Bubbles under the surface usually mean moisture is trapped underneath, often from failed waterproofing.

4. Faded or Peeling Color

Faded siding can signal that the waterproofing has worn off, leaving the home vulnerable to water damage.

5. High Energy Bills

Poor insulation due to old or damaged siding can drive up heating and cooling costs.

6. Dry Rot/ Insect Damage

Tap on the siding with a screwdriver; if it crumbles, you may have dry rot under the surface—something that spreads silently.
Insect holes or nesting between or under panels may suggest the siding is failing to protect your home.

7. Loose or Missing Panels

Siding that detaches easily or is completely missing sections needs immediate attention.

Lyle’s Pro Tip: Check the siding every 3-5 years to ensure there are no loose panels, bubbling, or warping.

Factor 2: A new roof will make the old siding look even worse

We all care about what our home looks like—and how it feels to come home every day. If you’re worried that new roofing with old siding (or vice versa) will look mismatched or outdated, you’re not alone. Let’s talk about how replacing both can make your home look its best.

When you replace only your roof or only your siding, you risk ending up with a home that looks a little “off.” Here’s what to consider:

Consistent Appearance:

Replacing both at the same time means your home’s exterior will match in color and style.

Avoiding Mismatched Aging:

If you do one now and the other later, you might end up with uneven wear and tear, which can affect your home’s curb appeal and value.

Factor 3: Will I Save Money If I Do Roof and Siding at the Same Time?

We all want to get the most value for our money, especially with big home projects. You might be worried about the price tag and whether combining jobs will really save you anything, or if it will just make things more complicated. Let’s look at what you can expect when it comes to your wallet.

If you’re thinking about replacing your roof and siding at the same time, you’re not alone—many homeowners are interested in the idea of saving money and hassle, and while it can definitely save you inconvenience, you’re unlikely to see any real cost savings.

Lyle’s Pro Tip: It’s a myth that you will see any significant savings by doing the two jobs at the same time. With that said, it can be easier to finance both at once.

Factor 4: Doing both can minimise disruption and make coordination easier

No one likes living through a construction project—the noise, the mess, and the disruption can be stressful. If you’re worried about how long this will take or how to manage your daily life during the process, you’re not alone. Let’s talk about what to expect.

Here’s what you should know about the logistics and impact of replacing both your roof and siding:

Time and Disruption:

While the upfront cost is higher, doing both projects together means just one construction period—usually 2–3 weeks for both.

Budgeting:

Clearly, the two jobs together are a bigger cost, so this may be a deciding factor.

Contractor Coordination:

Using one contractor for both jobs can make scheduling easier and ensure accountability.

Is it the Right Time for Me to Replace Both Roof and Siding?

Timing is everything—especially when it comes to big home projects. You might be wondering if now is the right time, or if you should wait until something breaks. Let’s help you figure out when to take the leap.

Here are some signs that it might be time to replace both your roof and siding:

Both Are Aging or Damaged:

If your roof and siding are both near the end of their lifespan or have visible damage, replacing both makes sense.

Energy Efficiency Goals:

For maximum energy savings, combine new siding and roofing with upgraded insulation.

Spring and early summer are the best times for exterior projects in Indiana, with milder temperatures and fewer weather delays.

Final Thoughts

Replacing your siding and roofing at the same time can be a smart investment, offering cost savings, improved appearance, better protection against Indiana’s weather, and long-term peace of mind. While the initial expense is higher, the benefits often outweigh the costs—especially if both are nearing the end of their useful life or have visible damage.

If your budget allows, consider bundling these projects for a smoother process and a more beautiful, efficient, and protected home. You’ll be glad you did!
